DENNIS HARRINGTON, OF,

BOSTON, MASSACHUSETTS Letters Patent No. 114,809, dated May 16, 1871.

IMPROVEMENT IN MACHINES FOR SCOURING, POLISHING, AND GLASSING LEATHER.

.i'he Schedule referred to in these Letters Patent and making part of the same.

It consists of a series of manipulators located on vertical circular tracks or frames, which are flattened ortruncated on their lower portions, formiug horizontal tracks immediately over the table on which the leather is placed, said manipulators being connected to and propelled by a wheel journaled between said circular tracks in such manner as to draw themanipulators along the table over the leather.

It also consists in certain details of construction, which will be more fully described hereinafter.

In the drawing- A represents the main frame-work of the machine, from'which depend the triangular frames B, in which are located the circular frames or tracks G O and the wheel D.

The tracks 0 are OOHHGCUBU oy transverse braces 0 and are flattened at their lower portions in such manner as to present horizontal surfaces, 0 over the table E, parallel with the same. 7

The brace G, which connects the upper portions of tracks 0, is provided with avertical standard or pillar, E, which passes through the frame A and terminates above the same.

G G represent-lugs on each side of standard F, between which lugs is journaled a cam-lever, H, which works in a slot in the end of standard F.

I I represent springs, which bear upward against arms J, which project from each side of standard F and thereby'suspend the circular ways 0.

Y K K, 850., represent mortised blocks between the circular ways 0, which blocks are provided with flanges k' 7:, which engage with said ways, and hold blocks K in position thereon in such manner as to enable said blocks to slide freely.

Each of the blocks K is provided with a holder or clamp, L, which rests in the mortise of such block, projecting from two sides thereofi-and has a slot along its outer edge, in which is inserted a manipulator, M, of stone-wood, or glass, the same being held by setscrews N N.

The inner side of holder L is provided with a projection or standard, 0, which passes through a cross-bar, P, which latter is attached to block K by braces Q.

R represents a spiral spring around standard 0, which, bearing against cross-bar P and holder L, forces the latter outward.

The blocks K are attached, by pivoted links or rods S, to' projecting arms '1 of wheel I), which is re-' volved by steam or other power, and, revolving, draws the blocks K, with their attachment, along the circular ways 0.

The frame-work, formed by the ways G and their braces O, is suspended from' the springs I, as above mentioned, and can be raised or lowered by raising or depressing the cam-lever H, the power of springs I being suflicient to raise said frame-work when the cam H releases the standard F.

' The table Eis movable, as .in other leather-scouring machines, and rests on several casters, U, each of which is provided with two rollers, V V, located at right angles with each-other, one at each end of block W,

which block is pivoted, through lugs X, to vertical rod or standard Y, on the lower part'of which is lo.- cated the circular nut Z, which constitutes a track for the roller V, thus enabling the caster to revolve readily in either direction and greatly facilitating the moving of table E.

Operation;

Power is imparted to the wheel -D, and the ways G are depressed to their lowest extent by the cam H, and the leather to be workedis placed on the-table E.

The blocks K are thus drawn across the table E, and the manipulators M are pressed by the springs R'upon the leather while passing along the horizontal portion of ways G, thereby imparting the desired finish to the leather, which can be varied by removing one manipulator, or all of one kind, and substituting others of different material.

The circular nuts Z can be screwed up or down on standards Y, thereby elevating or depressing the easters, raising or lowering the table E, and regulating the distance between said table and the ways 0.

Instead of the spiral spring It, a rubber 01' other spring may be employed.

Having thus fully described my invention,

What I claim as new, and desire to secure by Letters Patent, is

1. The circular ways 0, having horizontal portions 0 suspended from springs I, and depressed by means of the cam-lever H, substantially as described.

2. The mortised blocks K, prdvided with holders L, having manipulators M, standards 0, and springs In testimony whereof I have signed my name to R bearing against cross-bars P, substantially as dethis specification in the presence of two subscribing scribed.

3,. The blocks K, with their attachments, in combition with the ways 0 and wheel D, substantially as DENNIS HARRINGTON. described.

4 The casters U, having rollers V V at right Witnesses: angles with each other, pivoted to standard Y, and revolving on adjustable nut Z, substantially as dewitnesses.
